Take a regular mass film and multiply everything by three to get a sense of the scale of this Vijay-starrer.
Four kidnappings, three songs, two heroines, one flashback, one murder, a major twist and two Vijays and the film is just half done.
As long as the director manages to tie all the loose ends together in the second half, Mersal has the makings of being one of the biggest hits of the year.
